CANVAS-HOSE COUPLING.

Application filed August 8, 1916. Serial No. llfyoa` To all whom t may concern:

Be it known that l, NORMAN B. BRALY, a citizen of the United States, and a resident of Butte, in the county of Silverbow and State of Montana, have invented a new and Tmproved Canvas-Hose Coupling, of which the following is a fullpclear, and eX- act description.

This invention relates to hose coupling and particularly to. a coupling for canvas hose used in mines, and has for an object the provision. of an improved structure which is reversible and which may be quickly connected and disconnected at any time. d

nother object in view is to vprovide a spreading ring vin ad'dition to the coupler whereby the ring and coupler will hold the hose distended, the ring being supplied with means for suspending the hose.

A still further object in view is to provide a coupling for air hose which includes in its a wire or cable 3 construction slightly collapsing rings and a connecting sliding member, whereby the ring structure will always be maintained but maybe increased or decreased in diameter as' desired.

Tn the accompanying drawing z-Figure 1.

is a side view of a canvas hosew'ith an embodiment of the invention applied thereto, the various parts being shown in use.

Fig. 2 is a longitudinal vertical section through the abutting ends of hose and the coupling connected thereto. Fig. 3 is a plan view of the couplingy with a certain part broken away for better illustrating certain of the detail features. Fig. 4 is a sectional view through part ofvone of the hose sections showing a spreading and supporting ring embodying certain features of the 1nvention. Flg. 5 is a fragmentary detail' perspeetive view 'of the overlapping of the coupling rings and the means therefor. .Referring to the accompanying drawing by numerals, 1 indicates the roof or top of the passageway into which suitablesupporting members 2 are inserted for'supporting known as a messenger w1re. The passageway, wire 3 and associated parts are in common use in mines and therefore formV no part of the present inventlon, but

-UD to time and Whenever desired to any convenlent point, the convenience being in the ease with which the hose may be moved and lengthened or shortened.

The hose 4 is .made into a number of sections each section being connected by a coupler embodying the invention and intermediate the sections supporting and spreading means are provided embodying certain features of the invention, the same comprising an inner ring 5 and an outer wire or rod 6 held together at a suitable point by a hook l and eye structure 7. .The upper end of the-y wire is twisted at 8 and bent at 9 which hooks over the messenger wire 3 for properly supporting the canvas hose out of the way. lt will be observed that the ring 5 is provided with an inwardly extending bead 10 whereby an outer peripheral groove is` presented into which part of the .canvas is forced, as shown in Fig. 4, by the wire 6 so that the ring is always held v1n proper, position for spreading the canvas and also for su porting the wire 6.

he coupling asishown more particularly in Figs. 2 and 5 isformed from a metal ring 11 and a connecting plate 12. Thering 11 is provided with a turned-down langel and is divided or cut at one point so that `the ends may overlap, as shown in Figs.- 2

each other and move back and forth for varying the diameter of the ring in` order I that the ring on the end of one section of` hose may be inserted into the other. I t will be noted that the rings are reversiso that either end of any section may be either inserted into the ,end of the next adjacent section or over the end of the next adjacent section and the arts properly in,-

ble or, rather, the couplings are reversible,

terlocked. The ends of t e section of canvas are passed over the ringsv and are gstitched in'place by a line of stitching 17 for each ring, the rings being arranged so los that the iange 13 will be at the end. The

rings 11 aremade somewhat resilient so as to freely spread or become enlarged after having been contracted whereby the rings metal pipes for this purpose in temporary 1 fore undesirable.

galleries and other temporary parts of the mine, or where new passageways are being formed, is more or less expensive and there- The coupling and ring embodying the invention causes the use of canvas hose to be very acceptable in places of the kind just describechas the hose may be quickly and easily arranged in position by a minimum number of workmen, as each section may be independently carried and set up. Preferably the hose is suspended by hook 9, though this is not essential, as the hose may be laid on the floor or on any suitable system of projections, as the hose will readily conform to the shape of the passageway, which is-not true kof metal pipes unless a large amount of work is performed thereon.

What I claim is: p 1. A hose coupling. comprising a coupling ring formed with an inwardly extending flange, said ring being cut or divided at one position, the ring connected withone section of hose being capable of insertion into the next adjacent section of hose. v

2. In a hose coupling of the character described, the combination of a canvas hose divided into sections, a resilient metallic ring arranged at each end of each of said sections, said rings bein-g cut at onev point in order to overlap, a pair of slots in each of the overlapped portions or ends of said ring, said slots extending longitudinally of the rings, and a binding plate formed with a body itting against the ring and with retaining extensions projecting through said slots and overlapping part. of the material of the ring between the slots Awhereby the overlapped ends cannot become disengaged but may freely move longitudinally so as to vary the, diameter of the ring.

3. A coupling for canvas hose comprising a ring divided at one point and overlapped at the-divided point, said overlapped sections having `each a pair of longitudinally arranged slots, and a clip having arms extending from said` slots for preventing disengagement of the overlappingV sections while allowing a free longitudinal movement withinlimits, whereby the ring on the end of one section of hose may be f'orced into or from the ring of the next adjacent section.
